/**
 * WebResource extractor plugin for Channel4 4od.
 * 
 * Based on http://code.google.com/p/nibors-projects/downloads/list
 * 
 * @see for f4m issue http://code.google.com/p/get-flash-videos/issues/detail?id=379
 *
 * @author Petr Nejedly but modified to look at PS3 feed due to issue f4m files
 * This will take either standard web resource feeds from 4od:
 * eg http://www.channel4.com/programmes/happy-endings/4od
 * or will take PS3 feeds:
 * http://ps3.channel4.com/pmlsd/peep-show/4od.json?platform=ps3
 * Version 2 19 June 2013
